Hydroseeding in Armadale

Sand on the plain, clay near the hills

Armadale sits where the Swan Coastal Plain meets the Darling Scarp. On the flatter, western side, most new yards are sand or imported fill. Towards the hills, blocks have heavier clay and gravel.

Sand needs a wetting agent and soil improver. Clay needs loosening so water and roots can get in, and sometimes shaping so it drains in winter.

What we recommend for Armadale yards

• Prep matched to sand, clay or gravel
• A heavier mulch rate and tackifier on sloping blocks
• A hard-wearing couch blend for full sun
• Spring or early-autumn spraying

Sloping blocks near the hills

Closer to the escarpment, blocks start to slope, and bare soil on a slope washes in winter. We spray a heavier mulch layer with tackifier on sloping ground, and use erosion matting on the steepest batters, so the seed stays where it's sprayed while the roots take hold.
